Instruction Manual
45A and Above
Thank you for purchasing a Dragon X electronic speed controller (ESC). Our ESCs have been
constructed using the very best materials and assembly techniques and will give you many
hours of reliable use. It is important that you read these instructions carefully before use, in
order to become familiar with this ESC's functions and operation. Electric motors with any kind
of propeller can be very dangerous if operated incorrectly and could easily result in personal
injury. Children of 14 years of age or under should not be permitted to use this product without
direct adult supervision.
These ESCs have been designed for use in radio control model aircraft and helicopters only.

Basic Specifications
• Battery Type
Dragon X ESCs can be used with Li-Po or Ni-Cd/Ni-MH batteries. Default is automatic Li-Po
cell count (fully charged battery). The number of Li-Po cells can be precisely set if required.
This is recommended for packs of more than 3 cells. Use of Ni-Cd and Ni-MH cells can be
set. The cell count for these is automatic (fully charged).
• Low Voltage Motor Cut
This is set at 3v per cell for Li-Po and 0.8v per cell for Ni-Cd/Ni-MH
• Temperature Protection
At over 90°C, the motor power will cut (No Temperature protection for 110A)
• PWM Frequency
8KHz or 16KHz and is selectable. The frequency/signal is the way in which the motor and
ESC operate together.
Extra Automatic Functions
• Incorrect throttle position at power-up up will result in the motor not starting. The throttle must
be at the low position before the throttle is activated.
• An incorrect PWM signal will automatically turn off the motor.
• Lost signal protection - Loss of the PWM signal will automatically turn off the motor.
